Optical lens system for camera

Abstract

An optical lens system for photographing an object, according to an embodiment of the present invention, comprises an object image forming member for forming an image of the object, a light source for providing light to the object, optical lenses, an aperture stop area, and a switching aperture disposed in the aperture stop area. The switching aperture includes a base plate having, in the center thereof, an opening for an image to be taken, a blade having, in the center thereof, a pin hole for an image to be magnified such that a magnified image corresponding to the object is formed, and a variable connection member bent or straightened according to power supply to induce light incident from the object to form a photographed image via the opening for an image to be taken or form a magnified image via the pin hole for an image to be magnified.

Description

TECHNICAL FIELD[0001]The present invention relates to optical lens systems for cameras, and more specifically, to optical lens systems for cameras which are capable of flexibly performing a series of magnified image formation functions (i.e., object magnifying function) as well as basic captured image formation functions.DISCUSSION OF RELATED ART[0002]A recent remarkable development of electric / electronic technology leads to a sharp growth or spread of electronic devices (e.g., desktop computers, mobile phones, tablet PCs, game players, or laptop computers) that are equipped with an optical lens system for cameras (e.g., digital cameras) to carry out a series of camera functions in various manners.[0003]As shown in FIG. 1, an optical lens system 10 according to the prior art is systematically configured with an object image formation member 16 for forming a captured image corresponding to an object P, which has a CCD device or CMOS device for forming images disposed therein), optica...

AI Technical Summary

Benefits of technology

The present invention provides an optical lens system for camera that allows for flexible addition of a series of magnified image formation functions as well as its own basic captured image formation function even without attaching or detaching an additional lens system for magnified image or increase in the overall length of the product. This allows for easy addressing of various issues that the manufacturer or user of the electronic device may suffer due to a failure to form magnified images. The technical effects of the invention include improved quality competitiveness of the product and increased application of the product.

Problems solved by technology

Therefore, the user of the electronic device may get in trouble in using the camera optical lens system for magnifying object (Of course, as shown in FIG. 2, as the object P is brought closer to the optical lens system 10, the light beams 19 from the object P would form a dispersed focus with a larger width H2.)

However, the conventional techniques take such a raw approach as independently attaching or detaching a separate lens system for magnifying object from a camera optical lens system, which renders the same difficult to carry and use along with the electronic device.

Due to a failure to perform the magnified image formation function, the manufacturer or user of the electronic device suffers from various issues (e.g., a deterioration of quality competitiveness of the electronic device or reduction in application of the electronic device).

Therefore, the optical lens system for camera may easily address various issues (e.g., a significant deterioration of the quality competitiveness of the product or reduction in application of the product) that the manufacturer or user of the electronic device may suffer due to a failure to form magnified images by allowing for flexible addition of a series of magnified image formation functions (i.e., object magnifying function) as well as its own basic captured image formation function even without, e.g., difficulty in attaching or detaching an additional lens system for magnified image or increase in the overall length of the product.
